I posted some X1 gaming impressions here, sometime at the beginning of the year when the amazon.it offer started the craze. For the price I found it really good but the one-noty bass put me off in the end (+non-removable pads) and the highs while thankfull non-fatiguing aren't very detailed. It was 200€ though and that's still unbeatable imo.

The green Q701 I had a few days ago brought me back to the K701 memories (which I had for more than a year). While the AKG Soundstage is wide, it's pretty oval with not much depth and phantom center is lacking/diffuse. So in in terms of "huge", yes, they will overlap. Personally I would get something closed or special like the Fostex to complement rather than something "similar". Maybe Alpha Dogs turn out to be pretty good.

I really enjoyed all the reviews. This has to be one of the most detailed group of headphone reviews in every price range available. Congrats. Now I'm about to purchase a set of headphones and I'm torn between the MA900s and the Fidelio X1s. I really like the price/performance ratio of the MA900 but The X1s seem to be much better built and I do have the money for them. It's just that I don't want to spend almost $100 more for a very little increase in quality (soundwise). I'm going to use the headphones mainly for gaming (more non competitive), movies and music. My sources would be my gaming PC with a SBZ sound card and an HTC One as my portable music player. What would you recommend?? Thanks

As much as I love the ma900, if you have the money I'd suggest that you go for the x1. The materials and build quality seem well worth the extra money IMO. The jury is still out on just how well the ma900 will hold up over the long run. You'd definitely want to be gentle with them. my 2c...

That's exactly what I was thinking. Even if the audio difference between the two may be very little and who knows if I would even prefer the MA900s, build quality is very important for me regarding electronics and gadgets. This is the reason I got the HTC One instead of the S4.
